campaignUnsubscribesOutput output = unsubscribe.Execute(input);
Unsubscribers.AddRange(output.result.data);
string unsubscriber = "0";
//ArrayList a = new ArrayList();
//a[0] = output.result.data.ToString();
//List<MCItem> lst = new List<MCItem>();
// foreach (listBatchUnsubscribeResults order in myArrayList)
//{
// orders.add(order);
//}
string[] unsubs;
//ArrayList [] list = new ArrayList [0];
foreach (listMembers list1 in output.result)
{
unsubscriber = list1.ToString();
}
string unsubscribers = Unsubscribers.Count.ToString();
Page.ClientScript.RegisterStartupScript(typeof(Page), "alert", "<script language=JavaScript>alert('Unsubscribers:: '+ ' " + unsubscribers + " ');</script>");
//Unsubscribers.Reverse();
//dlUnsubscribes.DataSource = Unsubscribers.Take(10);
//dlUnsubscribes.DataBind();
//dlUnsubscribes.Visible = (Unsubscribers.Count > 0);
}

I would use Mailchimp Webhooks. You setup a page/script on your website which will get called by Mailchimp every time a particular event occurs. When it's an unsubscribe event, you can log the info you want to store to a database, file, etc.
